##### Order

Change the visual order of specific flex items with a handful of `order` utilities. We only provide options for making an item first or last, as well as a reset to use the DOM order.

First flex item
Second flex item
Third flex item

###### Code Example

    <div class="d-flex flex-nowrap bg-light">
      <div class="order-3 p-2 bg-light">First flex item</div>
      <div class="order-2 p-2 bg-light">Second flex item</div>
      <div class="order-1 p-2 bg-light">Third flex item</div>
    </div>

##### Align content

Use align-content utilities on flexbox containers to align flex items together on the cross axis. Choose from start (browser default), end, center, between, around, or stretch. To demonstrate these utilities, we’ve enforced `flex-wrap: wrap` and increased the number of flex items.
